Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 645169-3 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Number of Positions: 98
• Pitch: 0.100" (2.54mm)
• Gender: Female
• Number of Rows: 2
• Card Thickness Compatibility: 0.054" ~ 0.070" (1.37mm ~ 1.78mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish: Gold

Identified Substitute Parts:

1. 5645169-3 (TE Connectivity AMP Connectors) – Direct equivalent with identical electrical and mechanical specifications. Differs only in product status (Active vs. Obsolete) and RoHS compliance status.

2. 395-098-520-300 (Mercury United Electronics, Inc.) – Functional substitute meeting all critical position, pitch, gender, row, and termination parameters. Card type designation differs (ISA vs. Special 18/31 Dual Combo), but mechanical compatibility is maintained within specified card thickness tolerances.

Parameter Comparison

Engineering Selection Recommendations

5645169-3 (TE Connectivity AMP Connectors):

This part is the direct equivalent to the 645169-3 and is the primary substitute choice. It maintains identical electrical and mechanical specifications, including contact material (phosphor bronze), contact finish thickness (30.0µin), and operating temperature range (-55°C ~ 85°C). The primary advantage is active product status, ensuring continued availability. The part is RoHS Compliant, addressing regulatory requirements where the original part does not. Packaging is provided in Tube format with 1768 units in stock.

395-098-520-300 (Mercury United Electronics, Inc.):

This part functions as a secondary substitute when 5645169-3 is unavailable. It meets all critical mechanical and electrical compatibility parameters: 98 positions, 0.100" pitch, female gender, 2-row configuration, and compatible card thickness tolerance. Differences include contact material (copper alloy vs. phosphor bronze), reduced contact finish thickness (10.0µin vs. 30.0µin), and extended operating temperature range (-40°C ~ 105°C). The part is ROHS3 Compliant and REACH Unaffected. Selection of this substitute requires confirmation that the reduced contact finish thickness and alternative contact material are acceptable for the application's electrical performance and environmental requirements. Packaging is provided in Bulk format with 697 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 5645169-3 be used as a direct replacement for the obsolete 645169-3?

A: Yes. The 5645169-3 is a direct equivalent with identical position count (98), pitch (0.100"), gender (female), row configuration (2), card thickness tolerance (0.054" ~ 0.070"), mounting type (through hole), termination method (solder), contact material (phosphor bronze), contact finish (gold at 30.0µin), and operating temperature range (-55°C ~ 85°C). The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What are the key differences between the 5645169-3 and 395-098-520-300?

A: Both parts share identical position count, pitch, gender, row configuration, card thickness tolerance, mounting type, and termination method. Differences include: contact material (phosphor bronze vs. copper alloy), contact finish thickness (30.0µin vs. 10.0µin), operating temperature range (-55°C ~ 85°C vs. -40°C ~ 105°C), insulation material (polyester glass-filled vs. polyester thermoplastic), and card type designation (Special 18/31 Dual Combo vs. ISA). The 395-098-520-300 offers extended temperature capability but reduced contact finish thickness.

Q: Are there packaging differences between substitute parts?

A: Yes. The 5645169-3 is supplied in Tube packaging, while the 395-098-520-300 is supplied in Bulk packaging. Packaging selection may affect handling, storage, and integration into assembly processes.

Q: What is the significance of the contact finish thickness difference?

A: The 645169-3 and 5645169-3 feature 30.0µin (0.76µm) gold plating, while the 395-098-520-300 features 10.0µin (0.25µm) gold plating. Contact finish thickness affects wear resistance, corrosion protection, and long-term contact reliability. The thicker finish on the primary substitutes provides enhanced durability for extended service life.

Q: Does the card type designation (Special 18/31 Dual Combo vs. ISA) affect mechanical compatibility?

A: Card type designation reflects the connector's design series and intended application category. Both the Special 18/31 Dual Combo and ISA configurations maintain identical mechanical compatibility within the specified card thickness tolerance of 0.054" ~ 0.070" (1.37mm ~ 1.78mm). The designation does not prevent physical mating with compatible card edge connectors.

Q: What compliance certifications should be considered when selecting a substitute?

A: The 645169-3 is RoHS non-compliant and REACH Affected. The 5645169-3 is RoHS Compliant with undefined REACH status. The 395-098-520-300 is ROHS3 Compliant and REACH Unaffected. Selection should align with applicable regulatory requirements for the end application and target markets.

Q: What is the operating temperature range difference, and when is it significant?

A: The 645169-3 and 5645169-3 operate from -55°C to 85°C, while the 395-098-520-300 operates from -40°C to 105°C. The 395-098-520-300 provides extended high-temperature capability. Selection of this part is appropriate for applications requiring operation above 85°C or below -40°C, provided other electrical and mechanical parameters remain acceptable.
